Abstract (en)
[origin: EP0638511A1] A rope traction device includes a sheave (20) having an annular rope receiving groove (23) and being driven and rotated with a traction rope (22) received in the rope receiving groove to cause the traction rope to be wound on the sheave and the rope traction device thereby moves along the traction rope. The sheave includes a pair of side walls (24, 24) made of an elastic material and formed integrally with the sheave for forming the rope receiving groove. The interval between inner surfaces of the side walls (24,24) in a rope holding portion is made smaller than the diameter of the traction rope by a predetermined value. The rope receiving groove may be formed in a U-shaped section, a V-shaped section of a section which is a combination of the U-shaped section and the V-shaped section. <IMAGE>
